Abstract Scope |
Laser powder bed fusion is a commonly used technology within the space of metal additive manufacturing, but most machines are highly limited in the sizes of melt pools they can produce. Since melt pool size is directly tied to microstructural properties, expanding the range of possible melt pools produced is a desirable goal. By leveraging an alternative scan strategy, a systematic technique was developed to produce melt pools much larger than the typical melt pool size. This technique was mapped through process space using semi-analytical modeling, and the modeling was then calibrated using experimental data. Using the calibrated models, test parts were printed using parameters designed to produce large melt pools. |
